Realize and Realize Reader: Permitted URLs

Use the Permitted URLs list as a reference when configuring firewall and/or content filtering devices to allow access to the resources. View the full list.

Realize and Realize Reader Internet Connection

A bandwidth speed of 1 Mbps per user is recommended for optimal performance on all Realize and Realize Reader apps.

  • At School: The Realize application is a modern web application; the user's web browser will cache Realize for a period of 30 days or until a new version becomes available. It is estimated that an average of 12MB worth of data is transmitted per student per day. This estimate is based on a student usage session of seven page hits and downloading one content item.
  • At Home: Broadband via cable modem, DSL, or other high-speed Internet connection typically provides the recommended bandwidth.

Check your web cache settings. When properly configured, web caching may result in improved performance.

Additional Recommendations

  • Configure pop-up blockers to include *, *, *, *, and * in the list of allowed sites. If in doubt, check with your school's technology department for the proper browser pop-up and security settings. Disabling pop-up blockers is not recommended.
  • Enable JavaScript™ and cookies.
